<P>PROBLEM TO BE SOLVED: To provide a lubrication adjusting mechanism for a differential gear that can immediately supply sufficient oil to an insufficient lubrication part when there is a risk of causing seizure to the differential gear. <P>SOLUTION: The lubrication adjusting mechanism for the differential gear includes a steering angle sensor 74 detecting the steered state of a vehicle; an ECU 60 estimating the occurrence of a high differential state of the differential gear 20 based on the detected information; sensors 71-75 detecting the operated state of the vehicle; and a flow regulating valve 53 serving as a first quantity increasing means for increasing the supply quantity of oil to the vicinity of a drive shaft 31 or 32 on the high rotating speed side out of drive shafts 31, 32 connected to side gears 24a, 24b when the occurrence of the high differential state is estimated, and as a second quantity increasing means for increasing the supply quantity of oil to the vicinity of the drive shaft 31 or 32 on the high rotating speed side based on the detected information of the sensors 71-75 when the supply quantity of oil to the vicinity of the drive shaft 31 or 32 on the high rotating speed side is increased. <P>COPYRIGHT: (C)2011,JPO&INPIT |
